Our optimized warping method warps a volume in approximately 3 minutes per frame on an SGI Indigo 2. This represents a speedup of 50 over the unoptimized algorithm, without noticeable loss of quality. The running time is still dominated by scan-conversion and resampling, both of which can be accelerated by the use of 3D texture-mapping hardware.
